The Clipper's tang is pretty short, about halfway into the handle. There are other models with a longer 3/4th length tang.

If you go to google images and query "Mora 840 clipper tang" (no quotes) there are some x-ray pics.

Frankly I'm surprised they didn't go with a full length tang with the Robust (even if just a rat tail) to silence people's concerns about blade thickness and tang strength in one fell swoop. Mora's are apparently well regarded even without a full tang though.
